The James Webb Infrared Telescope photographed what is believed to be the most distant known star. This reports N+1 edition.

Initially, the star WHL0137-LS or “Eärendil” discovered in March 2021 with the help of the Hubble telescope. The star itself is located in the WHL0137-zD1 galaxy, and it was able to be seen in enlarged 9 thousand times with the help of the gravitational lens of the WHL0137—08 cluster. It is believed that this large star is an O-type star more than a hundred times heavier than the Sun, or an O-, B- or A-type star in the late stages of evolution is 40 times more massive than the Sun.

James Webb Watched "Eärendil" July 30, by the JWST Proposal 2282 program, which studies the images of gravitationally lensed stars using the NIRCam and NIRSpec instruments in the near infrared range. It is expected that these data will help to determine whether this star is really the most distant star known, as well as clarify its spectral type and evolutionary stage.
